Limited Fish Choices??

[mark]

Think about the fish's natural environment, some wrasse bury themselves in sand when frightened or sleeping, there's sand sifting and engineering gobies. Then of course the exceptions, pistol shrimp and goby pairs where someone on Canreef keeps on BB.

BB might also limit choices in coral.

Mandrins eat pods and you'll find them on rocks where you see the fish cruising.

Lawnmower is an algae eater, will do fine in a bare bottom as long as you have enough algae growing (hair algae). Mandarins eat pods, get some tiger pods and let them go for a couple months in the tank before you try to add a mandarin, there will be a nice population of pods for your fish. One thing to think about, bare bottom is fine but get lots of reef rubble for behind your larger rock, that gives your pods more hidding spots and safety from other predators.
